    Notes: Abstract Neurons in the olfactory deutocerebrum of the spiny lobster, Panulirus argus, were recorded intracellularly and filled with biocytin. Recorded neurons arborized in the olfactory lobe (OL), a glomerular neuropil innervated by olfactory and some presumptive mechanosensory antennular afferents. The neurons responded to chemosensory input from the lateral antennular flagellum bearing the olfactory sensilla but not the medial flagellum bearing many non-olfactory chemosensory sensilla. Many neurons received additional mechanosensory input. Thus the OL integrates specifically olfactory with mechanosensory input. OL neurons had multiglomerular arborizations restricted to one or two of the three horizontal layers of the columnar glomeruli. OL local interneurons comprised “core” neurons with tree-like neurites and terminals in the base of the glomeruli and “rim” neurons with neurites surrounding the OL and terminals in the cap/subcap. The somata of OL local interneurons lay in the medial soma cluster (100000 somata). OL projection neurons arborized in the base of the glomeruli and ascended via the olfactory glomerular tract to the lateral protocerebrum. A parallel projection pathway is constituted by projection neurons of the accessory lobe, a glomerular neuropil without afferent innervation but intimate links to the OL. The projection neuron somata constituted the lateral soma cluster (200000 somata).

    Notes: Abstract Neurons in the brain of the spiny lobster that respond to chemical and mechanical stimulation of the antennule (antenna I) were recorded and stained intracellularly. Described here are neurons that do not arborize in the olfactory and accessory lobes of the deutocerebrum, but rather primarily target the lateral and/or the median antennular neuropils of the deutocerebrum. Some of the neurons also extend into the antennal and tegumentary neuropils of the tritocerebrum and the neuropils of the median protocerebrum. Included are antennular sensory afferents, antennular motoneurons, projection neurons descending from the central brain, projection neurons ascending from the central brain and projection neurons descending from the eyestalk ganglia. Collectively, these neurons consitutute a novel antennular sensory pathway that is parallel to and independent of the antennular olfactory pathway. The novel pathway integrates mechanosensory and non-olfactory chemosensory information in the lateral and/or the median antennular neuropils, which also serve as lower motor centers of the antennule. Division of the arthropod deutocerebrum into two, functionally distinct chemosensory pathways may reflect differences in how chemosensory information is processed that is fundamental to understanding the origin of the sense of smell.

    Comparison of the expression of a plastidic chaperonin 60 in different plant tissues and under photosynthetic and non-photosynthetic conditions (1996)
    Springer
    Planta 200 (1996), S. 326-334 
    Details
    ISSN: 1432-2048
    Keywords: Chaperone ; Chloroplasts ; Chromoplasts ; Heat-shock protein ; Secale

    Topics: Biology
    Notes: Abstract A partial cDNA which codes for the β-subunit of a plastidic chaperonin 60 (cpn60-β) from rye (Secale cereale L.) leaves was identified and sequenced, except for 46 amino acids of the N-terminus of the mature protein and the transit sequence. This is the first cpn60-β sequence determined for a monocotyledonous plant. Specific antibodies against cpn60-β were affinity-purified from an antiserum raised against the total soluble protein fraction of ribosome-deficient plastids. The localization of cpn60-β in chloroplasts or non-green plastids was confirmed by immunodetection in Percoll gradient-purified organelles. The expression and occurrence of cpn60-β was analysed by immunoblotting with the specific antibodies and Northern hybridization. The cpn60-β protein was constitutively expressed in various green and non-green tissues. It was evenly distributed along the major part of a rye leaf, while highest transcript levels occurred in the youngest and oldest leaf sections. The expression of the cpn60-β protein was not enhanced by a heat-shock treatment at 42 °C. The cpn60-β transcript and protein were more strongly expressed in various non-green, for instance etiolated, 70S-ribosome-deficient 32 °C-grown, or herbicide-bleached tissues, than in green leaves of rye. A rapid increase in the cpn60-β transcript level was also observed when green leaves were transferred from light to darkness while the protein level was not affected. The dark-induced increase in the cpn60-β transcript was totally suppressed in the presence of 2% sucrose. Inhibitor treatments suggested that the change in cpn60-β transcript level was not related to changes of the ATP supply of the tissue. While the large subunit of the photosynthetic protein ribulose-1,5-bisphosphate carboxylase was largely degraded during ripening of tomato fruits, high levels of cpn60-β were detected in tomato chromoplasts and in the yellow flower petals of Narcissus. Low levels of cpn60-β were detected in root tissue.

    Notes: Liquid Crystals with Aliphatic Groups between Cyclohexane Rings - Synthesis of 1,4-Bis(4-n-alkylcyclohexyl)butanes and Esters of 4-[4-(4-n-Alkylcyclohexyl)-butyl]cyclohexanolsThe synthesis of 1,4-bis-(4-n-alkylcyclohexyl) butanes (1), esters of 4-[-(4-n-alkylcyclohexyl)butyl]cyclohexanols (2) and some analogous aromatic compounds are described. The thermal stability of mesophases of these compounds are in the order of the analogous ethylene-bridged liquid crystals. The reason for this result seems to be the combination of molecular rigidity and conformational flexibility.

    Photochemie und Photophysik von 3-(2-Isoxazolinyl)-phenylketonenHerrn Prof. Dr. E. Schmitz zum 60. Geburtstag gewidmet (1988)

    Notes: Photochemistry and Photophysics of 3-(2-Isoxazolinyl)-phenylketones3-Benzoyl-Δ2-1,2-oxazolines (1-6) are formed by 1,3-dipolar cycloaddition between benzoylnitril-N-oxide (8) and dihydrofurane 9 or 1,3-dioxep-5-enes (10a-c). The preparative yields are small due to the competitive dimerization of the dipole 8. Two stereoisomers are obtained by using 2-substituted 1,3-dioxep-5-enes as dipolarophiles. The different steric position of the substituents in 3-6 gives rise to different spectral data. The synthesized ketones possess triplet states with a high degree of charge transfer character. Therefore, the ability to H-abstraction reaction from alcohols is small. For ketone 2 and methanol as H-donor a rate constant of kHMeOH = 4,1 · 102 M-1s-1 is determined. Also by electron transfer reactions with triethylamine and some onium compounds the reactivity of the T1 of the ketones 1-6 is less compared to those of nπ* excited ketones. The photolysis of the ketones takes place very unselectively and leads to a product mixture. The quantum yields for the decay of the ketones are 10-2 to 10-3.
